| afcbf7 | deseven | 2025-06-12 12:02:54 | 47 | - hardware IDs are `1002:1586` (iGPU) and `1002:1640` (audio) |
| 0a91eb | deseven | 2025-06-19 23:08:35 | 48 | - Windows works fine, but I haven't managed to do it with a Linux VM, amdgpu driver crashes |
| 49 | - the 'reset bug' is here, I found no way to avoid it, so **you can passthrough the iGPU only once per boot of the host** |
|||
| 029502 | deseven | 2025-07-04 22:48:21 | 50 | - if your VM crashes during GPU driver install, switch the CPU type to something generic (`x86-64-v4` for example seems to work fine), install the driver, then return it back to `host` |
| 56c240 | deseven | 2025-07-04 22:54:19 | 51 | - if you see unknown PCI device (`1af4:1057`) in your Device Manager, install `viomem` driver manually from virtio drivers ISO |
| afcbf7 | deseven | 2025-06-12 12:02:54 | 52 | - set the fixed VRAM amount in the BIOS and never change it on the OS level, otherwise expect major slowdowns and crashes |
| 68c497 | deseven | 2025-06-12 11:47:12 | 53 | - [this issue](https://github.com/isc30/ryzen-gpu-passthrough-proxmox/issues/112) might be worth looking into |
